This article discusses the setting of the primary outcome measure, the need for it, the increased risk of false-positive and false-negative errors in secondary outcome results, how to regard articles that do not state the primary outcome, how to interpret results when secondary outcomes are statistically significant but not the primary outcome, and limitations of the concept of a primary outcome measure in clinical trial research. There are 2 reasons for this: it reduces the risk of false-positive errors resulting from the statistical testing of many outcomes, and it reduces the risk of a false-negative error by providing the basis for the estimation of the sample size necessary for an adequately powered study. While it is a helpful tool, it is an imprecise method and is best used as a supplement to the many other ways we measure homelessness. It provides data used for federal funding allocations and national estimates of homelessness. The primary outcome needs to be defined at the time the study is designed. The Point-in-Time Count is a census of sheltered and unsheltered people experiencing homelessness on a single night. With this type of data we are looking at. ![]() Use the Copy Outcome button to create an Outcome Measure for each time point.The primary outcome measure is the outcome that an investigator considers to be the most important among the many outcomes that are to be examined in the study. So, instead of looking at an observation at one point in time, we will look at data from more than one point in time. The Copy Outcome button is located below the Outcome Measure fields. Just don’t forget to update the title and time frame for each one! If you are NOT measuring and reporting a value of change between two time points for your outcome measure, write your outcome measure, and then use the “Copy Outcome” button to duplicate it for each time point. Option 1 : Not assessing a change (most common). This can be a frustrating requirement, but it is easily addressed: For example, if March 2001 has a higher original. Unless you are measuring a value of change over time, Time Frames for Primary Outcome Measures must have only one time point per outcome measure, or the record will be rejected. If we compare year apart data in the original series, we may miss turning points occurring during the year. Time Frames for Primary Outcome Measures must have only one time point, or must be assessing a change between 2 time points. Synonyms for point in time include moment, juncture, stage, occasion, crisis, interval, pass, time, point and instant. Hospital admission to discharge (about 3 days).If you have a large visit window, or you are collecting a time-to-event outcome measure, such as “days until progression”, use “About ” or “Up to ” to describe your Time Frame. a system of measurement: give the size in metric measure. a device for measuring distance, volume, etc, such as a graduated scale or container 3. It is not the overall duration of the study. the extent, quantity, amount, or degree of something, as determined by measurement or calculation 2. Week 6) when you will be collecting the outcome measure data for each participant. ![]() The Outcome Measure Time Frame is the specific time point or window (e.g. Outcome Measure Time Frames need to be specific. It is not the overall duration of the study. Unless you are measuring a value of change over time, Time Frames for Primary Outcome Measures must have only one time point. Outcome Measure Time Frames need to be specific.Outcome Measure Time Frames need to be specific.The requirements for Outcome Measure Time Frames can be summed up as: ![]() One of the most common sources of QC comments that cause records to be rejected is the Outcome Measure Time Frame field.
